My ancestress Dicy, born 1824 or 1825 in NC, shows up on the Cocke Co., TN 1850 census, married to John P. Holland.John P. Holland was born in Cocke Co., TN, in 1823 or 1824.Judging from the names of her children and grandchildren, she may have been an Allen.Might anyone recognize this lady?The census information is all I have!
